T0 ail whomfltvmy concern: Be it known that I, EZRA E. Goon, a citizen of the United States, residing at Waterloo', in the county of Blackhawk and State of Iowa, have invented certain new and useful Im rovements in Milkin Apparatus; and I do hereby declare the fofi'owin-g to be a. full, clear, and exact description of the invention, such as will enable others skilled inthe art to which it appertains to make and use the same My invention relates to milking apparatus I of the type wherein pulsating devices are employed, and has for its object to provide improvedmeans'fo'r controlling the delivery of milk from the milk tubes into the cans.

To the above ends, the invention consists of the novel devices and combinations of devices hereinafter described and ,de'fined in the claims 7 s:

' out of the can, isnot neces In the accompanyin drawings whichillustrate the invention, li e characters indicate like partsthroughout the several views.

Referring to the drawings: F igurel is a view in side elevation with some parts broken away; showing the improved device applied to a milk can Fig. 2 is a plan view of the same;

1 andFig, 3 is a vertical section taken on the line 00 x of Fig. 2, some parts being broken away and some parts being removed.

The numeral 1 indicates a milk can of suitable constru'ction, having, as shown, alarge neck portion 2 normally closed by a cover 3. For the purposes of this case,'it is not necessary that the cover 3 close the can with an air-tight joint, and in fact, the said cover, while a desirable feature in order to keep dirt sary to the operation'of the imp'roveddevice.

In its preferred form, this improved device for controlling the delivery of the milk into the can, comprises an outer casing 4, having an internal cylindrical piston valve seat 5 that is open both at its upper and lower ends, and the lower end of which projects downward into the can 1 the said casing i being suitably secured to the can.

One or more milk inlet sleeves 6 open into the casing l, preferably near the lower portion thereof; and. a milk supply tube 7 is connected to each sleeve 6'. Each milk tube 7 is connected to one or more teat cups of suitable construction.

An air suction tube or pipe 8-8 leads from the top of the casing 4, and extends, preferably to a main air suction pipe, which m'turn, is connected to asuitable air pump seat 5.

f for. producing the required suction or vacumilk induction port 9, that opens into the bottom of the milk collecting chamber 10, which latter is formed within the casing 4 outside of the valve seat 5. r

Working in the valve seat 5,. is a heavy cylindrical piston-like valve 11 having a depending stem '12, to which a secondary valve 13 is attached. The downward movement of the two valves 11 and 13 is limited by a stop collar 14 applied, to the lower ends of the valve seat 5, and engageable witlrthe valve 13. at 15 to afford discharge ports.

The air suction pipe above described, is shown as made up of a crooked metal section 8 and a rubber hose 8, which latter, of course, permits the canl to be movedabout.

The operation of. the device is' as follows: Normally, the connected valves 11 and 13 tions, shown in Fig'. 3, in which position said valvell closes the port 9. When suction or partial vacuum is produced in the pipe 88, and also, of course, in the collecting chamber this same suction or partial vacuum will raise the valves 1-113, thereby causing the former to open up the port 9 and the latter to close the extreme lower end of the valve When the port 9 is thus opened up, the milk drawn into the collecting chamber 10 will, under the action of gravity, flow through said )ort 9 into the valve seat 5 between the va yes 11 and 13 Then, when the suction or partial vacuum is released by admission of air into the airpipe 88by their normal positions, shown in Fig. 3, thereby closing the port 9 and opening up the lower end of the valve seat 5, so that the milk accumulated in the said valve seat will pendent of whether or not the milk can. is open to the atmosphere. In fact, the said can will preferably be subject to atmospheric pressure at all times.

9 hat I claim is:

1. In a milking apparatus for producing pulsations, the com ination with a milk supply tube and an air suction conduit connected therewith, of a valve mechanism arranged to intermittentl connect a chamber to said milk suppl tu e and to a discharge port, substantia ly as described.

'2. In a milking apparatus, the combination with a milk can or receptacle, of a casing having a valve seat arranged to discharge into said receptacle, a milk supply tube leading to said casing, an air suction tube leading therefrom, a primary valve working in said valve seat subject to varyirom within said casing, and arranged to 0 en and closea port in the lower portion 0' the said casing,

havin means and a secondary valve carried by. the said primary valve, and arranged to close the ower' end of said valve seat when said primary valve is ra1sed,; and to open the same when said primary valve s lowered. substantially as described.

3. In a milking apparatus havin means for producing pulsat ons, the com ination with a milk can, of a milk supply tube,'an

air suction conduit connected to said milk supply tube, and a valve mechanism subject to pulsations and arranged to intermittently connect a valve controlled chamber to said Witnesses: I
